Ramp Plan Symbol...?

Group,

Drafting a ramp in plan - can someone tell me what is the correct symbol orientation to indicate direction of slope?

* please see attached image *

Thanks,

I seem to see this convention used in Euro books more than US publications.  Neufert Architect's Data shows it with the apex at the top, or hinge of the ramp.  The way I forced myself to remember it is that if i spilled a glas of milk at the top of the ramp, them it would spread out like the line do.

 

I always find it best to label the ramp so there is no confusion instead of relying on this convention.

I've never seen a ramp denoted that way. Just an arrow and and "up" or "down."

What do the long diagonal lines signify?

By typical convention, lines such as these indicate a change in the plane of the surface. But, to be consistent, the (assumedly) flat landing at the end of the line intersection in the middle of the joint would have some sort of similar lines extending away from the (low?/high?) point.

As far as the arrow and notation go, I usually extend the arrow and leader the entire length of the ramp to assist in defining the start and end point of the sloping surface.

Can't say for sure which one is correct, but image "A" seems more natural
and is what I've seen most of on Arch Plans, but what do I know!

II don't know your background or that of Chas, but just to note, I''ve been a licensed architect for over 20 years, after about a dozen years prior drafting experience, and I've never seen such an indication at all. I happen to know teiarch also has a long background in architecture.

And both of us are going, "Huh?" Like he said, I see no need for the diagonal lines, which would appear to falsely iindicate changes in plane. I don't know where this supposed convention came from, but it's completely alien to me.

I run into this quite a bit working with legacy drawings of public works,
like airports and stadiums. We are given seed drawings of lease areas for
retail and food service development.
At first I asked questions of the DOA Engineering to determine the exact
meaning and direction. I didn't question the source of their conventions.

Interesting. Maybe it's industry-specific.. I've worked with hundreds of business/commercial site plans and never encountered this. Frankly it looks clluttered and confusing to me.

Almost every "cabinet" elevation drawing I've ever seen uses this type of
symbolism. The vertex is at the hinge side of the doors. Have you ever seen
such?

sure - doors too. but, ramps don't open (well, if they did - it would make
for a heck of a ride). ;-)
